This question is giving me trouble.
So the correct answer is (E) and i guess it is supported by lines 16-17, where it says "when embryos are in the process of forming their nervous systems, they produce many more nerve cells than finally REQUIRED." Also the fact that in the last sentence of the passage, the author kindly informs us (line 55) "...the TYPES of nerve cells that ARE affected by NGF," seems to imply that not all nerve cells would be affected by NGF. Is this reasoning alrite?
But the problem is (C). How are you supposed to understand the word 'few'? It just means same thing as some, but may have a slight negative connotation just as 'many' may have a postiive one, right? But in any case, they would all boil down to the same meaning? Given such understanding of 'few', this answer choice basically means that 'some nerve cells that connect with target cells assisted by NGF are needed by the organism?" Ok so what i want to ask is, is this not the correct answer bc even though presumably, the cells would be necessary for the organisms, the passage doesnt explicitly provide info regarding the necessity of some nerve cells in relation to the organism per se? In other words, unlike (E), there wouldnt be a specific line reference where we can put our finger on
Would this be a good reason?
